Brief Description: Rivet Flaperon Hinge Assemblies
The plans call for the bearing to be squeezed into the central plate on each hinge assembly before riveting. The suggestion is to use a c-clamp or a vice with a 7/16th socket pressing on the bearing and a 9/16th socket acting as a spacer behind the plate. I found a 5/8th socket to be easier. I was pleased to note that the ball rotated freely in the sockets after pressing and, indeed, after insertion of all of the rivets.
Picture 1 shows the bearing in place, the three-layer sandwich riveted together with solid rivets, and the assembly pop-riveted to the spar doubler. Big mistake! These should not be pop rivets. So this is my first opportunity to try drilling out pop rivets. I had previously purchased some size 31 drills. These are just undersize (a 30 drill is for 1/8 inch rivet holes). This did the job, and the rivet heads broke off cleanly. I pushed the tail through using the dimpler and a spacer, as Robin had shown me. Hey presto, 8 rivets removed and no damage. This is actually Page 14-03 Step 2.
Picture 2 shows the job redone properly. Interestingly, I see I have put the flush rivets on the opposite side to the round headed rivets on the right-hand assembly. Didn't notice at the time.
